LrC 13.2 AI denoise too slow intel ultra 7 155h

Hello all, I use a Lenovo laptop with the following parameters: Intel ultra 7 155h / 32 GB RAM / Intel Arc GPU, WIN 11 and the AI ​​denoise process for one photo (24 mpx) takes about 4 minutes. Is there any way to speed this up or do I just have weak HW? During the AI ​​denoise process, the GPU is fully utilized, but the NPU is idle. Is this standard behavior? Thank you.
